Having trouble with $_GET variables

[eluser]rebellion[/eluser]
I read this explanation on how to get $_GET variables accessible for my method, but it won't work. I've tried all the available URI protocols in the config.php.

The thing is; I'm using an SMS service that allows users to send a text message to a number. The service will then send the SMS content as GET variables to an URL. I could write a script that process the incoming data, but it involves a bit of database handling and checks, and should then simply echo out "OK".

I want to be able to do this with an SMS controller, instead of a non-CI script. The controller/method URL looks like this:
http://mydomain.com/sms/receive_sms/

The SMS service sends the variables as follows:
http://mydomain.com/sms/receive_sms/?msg...&message=x

But those variables are unaccessible for me, even though I followed this guide: http://ellislab.com/forums/viewthread/99570/

Did you try the other uri_protocols?

You can do in this way with your own custom uri helper:
function uri_assoc($var, $segment = 3) {

$CI =& get_instance();

$uri_assoc = $CI->uri->uri_to_assoc($segment);

if (isset($uri_assoc[$var])) {

return $uri_assoc[$var];

}

else {

return NULL;

}

}



$this->load->helper('uri');
uri_assoc('msgid',2);
uri_assoc('number',2);
uri_assoc('message',2);
